Echo语句在echo语句中不起作用

Question

echo '<li><a href="signup.html"><span class="glyphicon glyphicon-user"></span>Welcome echo $_SESSION["username"];</a></li>';

In the above code it is not displaying username variable.. instead it is simply echoing Welcome $_SESSION["username"];

FYI.. I have used session.start() in both the files

But how to display Welcome 'username'

Answer 1

The part Welcome echo $_SESSION["username"]; is simply a STRING and would be echoed verbatim without any Evaluation, Processing or Parsing. And, by the way: You don't use an echo Statement within an echo statement. That should be like SAYING GOOD MORNING IN ENGLISH & GERMAN AT THE SAME TIME THROUGH THE SAME ONE SINGLE MOUTH: LOL :-)

You should have used Double Quotes to surround the String you wished to echo out and then use single quotes for the HTML DOM Element Attributes like "class" or "HREF". That way you, you could very easily echo your String without much fuss. Here's how:

    <?php

        echo "<li>
                <a href='signup.html'>
                    <span class='glyphicon glyphicon-user'></span>Welcome {$_SESSION['username']}
                </a>
            </li>";
